Though the Dauki Fault Zone is shown as a single fault line on the geological map of Bangladesh (1990) but the images show that it is the combination of a number of en-echelon faults trending in different directions, making the fault scraps zigzag rather than a straight line.
Earthquakes in Bangladesh are frequent and often cause damage. The earthquakes occur due to a convergent boundary between the Indian Plate and the Eurasian Plate . Earthquakes

Earthquake epicenters 1963–98. In seismology, a seismic zone or seismic belt is an area of seismicity potentially sharing a common cause. It can be referred to as an earthquake belt as well. It may also be a region on a map for which a common areal rate of seismicity is assumed for the purpose of calculating probabilistic ground motions.
Map updating is a regular process and done once every five to seven years. At present the SOB is digitally updating the base map of Bangladesh. The SOB publishes all the maps from its own offset printing press and the products are available in its sales centre at the SOB campus located in the Tejgaon Industrial Area, Dhaka-1208.
The 1997 Chittagong earthquake (also known as the Bandarban earthquake) occurred on 21 November at 11:23 UTC in the Bangladesh-India-Myanmar border region. It had a magnitude of M w 6.1. The epicenter was located in southern Mizoram , India.
The 1948 seismic codes were prepared in consideration of the seismic zone map. A new code was revised in 1961 and in 1963, the seismic zonation map was updated with four hazard levels based on predicted shaking on the Modified Mercalli intensity scale. It was subsequently added a fifth hazard level in the 1972 revision. [12]
Bangladesh map of Köppen climate classification zones. Heavy rainfall is characteristic of Bangladesh, causing it to flood every year. Except for the relatively dry western region of Rajshahi, where the annual rainfall is about 1,600 mm (63.0 in), most parts of the country receive at least 2,300 mm (90.6 in) of rainfall per year.
